Hi, I noticed some time ago that, for instance, named vectors that are really makes str() really slow when displaying the names attribute. I don't know exactly when this started, but it wasn't the case say 1-2 years ago. Example (on a WinXP 1.8GHz): > s <- 1:1000; names(s) <- s > system.time(str(s)) Named int [1:1000] 1 2 3 4 5 6 7 8 9 10 ... - attr(*, "names")=

I'm trying to troubleshoot a case where R crashes on Windows. It does not occur at all with my R v2.1.0 patched (2005-05-09), but happens on R v2.1.1 (patched or non-patched) in many different cases. The R v2.2.0dev (2005-07-15) also got this problem (although it won't crash on the below example). I previously reported this

Hi, help on 'mahalanobis' (in the stats package in Rv2.2.0) now says: "Description: Returns the Mahalanobis distance of all rows in 'x' and the vector mu='center' with respect to Sigma='cov'. This is (for vector 'x') defined as D^2 = (x - mu)' Sigma^{-1} (x - mu)" It does return D^2 as written. However,

Hi, I've got a version of rowMedians(x, na.rm=FALSE) for matrices that handles missing values implemented in C. It has been optimized for memory and speed. To avoid coercing integers to doubles, and hence allocate an additional 200% memory, there is one C function for integers and one for doubles. The rowMedians() implementation is currently sitting in my non-CRAN package R.native

I use smooth.spline(x, y) in package modreg and I would like to get value of penalized log likelihood and preferable also its two parts. To make clear what I am asking for (and make sure that I am asking for the right thing) I clarify my problem trying to use the same notation as in help(smooth.spline): I want to find the natural cubic spline f(x) such that L(f) = \sum_{k=1}{n} w[k](y[k] -

x <- rnorm(1e6); y <- log(x); # or logb(x) or log1p(x) w <- warnings(); print(object.size(w)); ## [1] 480 str(w); $ NaNs produced: language log(x) - attr(*, "dots")= list() - attr(*, "class")= chr "warnings" y <- log2(x); # or log10(x) w <- warnings(); print(object.size(w)); ## [1] 8000536 str(w); ## List of 1 ## $ NaNs produced: language

>From NEWS of R v2.6.0 devel: o R CMD check now does a recursive copy on the 'tests' directory. However, R CMD check does not run *.R scripts in such subdirectories (as I thought/hoped for), only those directly under tests/, This may or may not be intentional. If true, maybe the above should be clarified as: o R CMD check now does a recursive copy on the 'tests' directory

The VALUE section in the help for 'unlink' says: | 0| for success, |1| for failure. Not deleting a non-existent file is not a failure, nor is being unable to delete a directory if |recursive = FALSE|. However, missing values in |x| result are regarded as failures. The last phrase doesn't make sense to me. Should it be either "missing values in x are regarded as

Full_Name: Henrik Bengtsson Version: rw1022 OS: Windows Me Submission from: (NULL) (216.175.126.55) When ${R_HOME}/share/perl/maketitle.pl tries to generate a TITLE that is longer than $lc-3 (=13) characters long, it repeats the package name on line two. Example: Now it generates an output like: com.braju.graphics com.braju.graphics Bla bla bla... But, I believe it should

Is there a way to convert between and integer and a character and vice versa? For instance i <- 65; ch <- intToChar(i); # "A" i <- charToInt(ch); # 65 or even better i <- c(65, 66); ch <- intToChar(i); # c("A", "B") i <- charToInt(ch); # c(65, 66) I have tried to do a ASCII map myself, and I figured out that the ASCII

Full_Name: Henrik Bengtsson Version: 1.3.0 OS: Windows Me Submission from: (NULL) (216.175.122.171) I realized that the title of packages in the library index when they are in a bundle is the title of the bundle and not the package. It looks like the TITLE file, which apparently is used for generating the library index, takes the value of the bundle's title and not the package's title.

I'm frightfully new at developing r packages. I'm developing an econometrics package, and each time I update my beta package, I close R, delete the package dir in the library dir, rebuild the zip file, rerun R, reinstall the package and run the functions. Is there a more efficient way? Jeff. Jeff D. Hamann Hamann, Donald & Associates, Inc. PO Box 1421 Corvallis, Oregon USA 97339-1421

Is there an inverse function to 'which' available, which creates a logical vector/matrix from indices? I wrote my own, but if there is a standard function I would like to use that instead. Example: x <- c(TRUE, TRUE, FALSE, TRUE, FALSE, FALSE) unwhich(which(x)) # [1] TRUE TRUE FALSE TRUE unwhich(which(x), length(x)) # [1] TRUE TRUE FALSE TRUE FALSE FALSE y <- matrix(x,

Is there a way of echoing (similar to Matlab "echo on") commands that are being executed? I know how to do this for script files by using source(..., echo=TRUE), but I would like to be able to use this within *any* function. I am also not looking for the debug() function. Here is what I would like to do: myFunction <- function() { echo(TRUE); x <- 3; cat("x = ", x,
